CHURN.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application tiled April 14, 1909. Serial No. 489,919.

To all whom it may concern:

Be it known that I, RICHARD ELLIOTT CoULTI-IARD, a subject of the Kingof Great Britain, residing at St. Marys, in the county of Perth andProvince of Ontario, Canada, have invented certain new and usefulImprovements in Churns, of which the following is a specification.

My invention is in connection with improvements in churns, but relatesmore particularly to churn-frames and means supported thereby foroperating the barrel, and the objects of my invention are, firstly, toprovide a very strong, stiff, and yet light churn-frame, and one whichcan be readily tilted, and moved to wherever desired; and secondly, toprovide a drive-gear for the barrel so that the same can be rotated at aspeed in keeping with the amount of cream held thereby, and with theleast possible exertion on the part of the operator.

A third object of my invention is to construct the churn-frame so thatthe barrel may be readily placed thereon and removed therefrom.

The construction of my invention will be hereinafter particularlydescribed, and the parts I claim as new will be pointed out in theclaims forming part of this specification.

Figure 1 is a perspective View of my improved churn-frame, and theoperating-gear for the barrel. Fig. 2 is a longitudinal Vertical sectionthrough the head of the churnframe showing the preferred manner in whichthe drive-shaft is mounted. Fig. 3 is an enlarged vertical crosssectionthrough one end of the head of the churn-frame, and the uprightsassociated with this end, showing details of construction. Fig. 4 is adetail view showing a side elevation of the bearing, and Fig. 5 is aperspective View of the preferred form of bearings I use.

In the drawings, like characters of reference indicate correspondingparts in each figure.

My churn-frame is mainly constructed of members made of angle-ironsuitably braced by members made of band-iron.

A and B are the vertical uprights which are bent at their upper ends,and extended downward and outward so as to form the front members C andD. The vertical upright A and the front member C are secured at theirlower ends to the horizontal member E, and the vertical upright B andthe front 7 member D are secured at their lower ends to the horizontalmember F, in the position shown.

G and H are braces secured to the horizontal members E and F.

As before mentioned, the vertical uprights and the front members arepreferably formed integrally, and in order to secure the sleeve I to thesaid uprights and members, the flanges of the front member D and uprightB, respectively, are cut away as shown at (Z and b, Fig. 3, thuspermitting the said sleeve to be snugly fitted to the said uprights andmembers. By any suitable means, such as the bolts or rivets 2, the saidsleeve is secured in place.

3 are a pair of braces extending from the front members C and D to thesleeve I.

4 are a pair of braces attached near the lower ends of the uprights Aand B and secured at their upper ends to said uprights so as to bracethem together.

5 and 6 are struts secured at their lower ends to the longitudinalmembers E and F respectively, and secured at their upper ends to thefront members C and D respectively.

7 is a bar secured at each end to the vertical uprights A and B. Thisbar firmly supports the lower ends of the said vertical uprights inrelationship to each other.

The corners of the churn-frame formed by the conjunction of the frontmembers C and D with the horizontal members E and F are each supportedby a knee 8 which is secured at its upper end 9 to its associated frontmember, and secured at its lower end 10 to its associated horizontalmember. It will be noticed that these knees are bent to form a downwardloop 11, which loops rests upon the floor'and so supports the saidhorizontal members thereabove. Likewise at the point of juncture of thevertical uprights A and B with the horizontal members E and F, I provideknees 12 and 13 which are constructed substantially the same as theknees 8. As these sets of knees are of the same height, the members Eand F will be held in a horizontal position.

In order to permit my churn-frame to be readily moved, I suitably mountin the same a pair of caster-wheels. According to the construction shownfor mounting these caster-wheels in the frame, it will be seen that Iextend the vertical flange e of the horizontal members E and F backbeyond the vertical uprights A and B, as shown at 14, thus forming oneof the members wheels are mounted.

between which the caster wheels 215 are mounted.

16 are plates suitably secured to the lower portion of the frame, forinstance, to the vertical uprights and the horizontal members, and thesaid plates form the inner bearing members in which the said caster Inorder to shift the churn-frame, it is only necessary to tilt the same onthe said caster-wheels, and move it in the desired direction, as will beunderstood. The bar 7 is used as a brace against which the foot isplaced when it is desired to tilt the churn-frame in order to move it.The sleeve I held by the vertical uprights and front members forms whatI call the head of the churn-frame, and it will be understood that inorder to tilt the churnframe it will be most convenient to grasp thesame by the head at the same time the foot is placed against the bar 7.

Mounted in the sleeve I is the driveshaft 17. This drive-shaft is heldin bearings 18 mounted within the sleeve I.

19 and 20 are washers mounted on the drive-shaft l7 and against theirassociated ends of the sleeve I. The drive-pulley 21 is keyed to one endof the shaft 17.

22 is a split pin or other means passing through the shaft 17 andoperating adjacent the washer 19. By means of this split pin it will beunderstood that the shaft 17 and its associated parts are retained inplace.

23 is any suitable handle by means of which the shaft 17 is turned.

I may use any make of barrel with my churn-frame, as will be understood.The barrel illustrated is provided with the usual trunnions. 011 one ofthe trunnions 24 is secured the driven pulley 25. The belt 26 of coursetransmits motion from the drive pulley 21 to the said driven pulley. Thedriven pulley is of course of a smaller diameter than the drive-pulley,thus enabling me to get the desired number of rotations of the barrel toone turn of the crank or handle 23.

The churn-frame may be provided with any suitable hook 27 which engageswith an eye 28 carried by the barrel 29. The means just described or anyother suitable means is used to hold the barrel in the desired positionwhen it is not operated.

I may use any suitable construction for mounting the trunnions of thebarrel in the churn-frame, but prefer to use the bearingbrackets forthat purpose to be now described. The bearing-brackets 30 are formed toprovide pockets 31 in which rest the blocks 32 in which have bearing thetrunnions of the barrel. The pockets 31 are formed with vertical sides33 and 37. The vertical side 33 is formed integrally with an extension35 which is secured at 36 to the top flange of one of the front members.The

vertical side 37 is extended above the verti cal side 33, and it isintegrally formed with the leg 38 which is secured at 39 to the topflange of one of the said front members. The formation of the verticalside 37 and the leg 38 form the loop 40. The top of this loop is curved,as shown, and as the corner 41 between the extension 35 and the side 33is rounded, it will be understood that the said bearing-brackets areconstructed so that the blocks may be readily placed into and removedfrom, the pockets 31.

42 is a threaded rod which extends through the vertical upright 33 ofone of the said brackets and threads through thetop flange of one of thesaid front members. The head of this threaded rod performs the functionof a key so as to lock the block of the driven pulley 25 down in itspocket so as to prevent the trunnion 241 from being displace I desirenot to be limited in the construction of my invention beyond therequirements of the prior art and the terms of my claims.
